Comparison of nasal Midazolam with Ketamine versus nasal Midazolam as a premedication in children

Abstract

Background:This study was done to compare effects of intranasal midazolam and intranasal midazolam with ketamine for premedication of children aged 1-12 yrs undergoing intermediate and major surgeries.Aims:Midazolam and Ketamine have already been used as premedicants in children. Our aim was to find out advantage of combination of midazolam with ketamine over midazolam by nasal route.Methods:Sixty children of age group 1-12 yrs of American Society of Anesthesiologists (ASA) grade 1 and 2 were selected. Group A- midazolam (0.2 mg/kg), Group B- midazolam (0.15 mg/kg + ketamine 1 mg/kg). Both groups received drug intranasally 30 min before surgery in recovery room with monitored anesthesia care. Onset of sedation, sedation score, emotional reaction, intravenous cannula acceptance, and mask acceptance were studied.Statistical Analysis:Unpaired t test and chi square test.Results:Sedation score, anxiolysis, attitude, reaction to intravenous cannulation, face mask acceptance, and emotional reaction were significantly better in midazolam with ketamine group. Intra operatively, in both groups, pulse rate, oxygen saturation, and respiratory rate had no significant difference; also, post operatively, no significant difference was observed in above parameters, post operative analgesia was significantly better in midazolam with ketamine group.Conclusions:Intra nasal premedication allows rapid and predictable sedation in children. Midazolam as well as combination of Midazolam with ketamine gives good level of sedation and comfort. But quality of sedation, analgesia, and comfort is significantly better in midazolam with ketamine group. No significant side effects were observed in both groups.
